So how do I detect bull2bear or bear2bull changes with finished candles?
With regular candles I could use the index (1=the last one, 2= the one before and so on)
With HA I don't see something equivalant.
What I see with HA is, that it fires whenever a change happens, while building the candle. This might or might be not valid for the final candle.
So what I need is something like "HA Candle 1 was bear and HA Candle 2 was bull => changed", so I can attach this to "once per bar" block.
Is this achievable?
And I'm not sure, how trace can help me out here.
